样例脚本:
# -*- coding: utf-8 -*-
from selenium import webdriver
import os
#credentials
USERNAME = '##########'
PASSWORD = '#####$####'
#load profile
profile = webdriver.FirefoxProfile()
profile.set_preference('browser.download.folderList', 2) # custom location
profile.set_preference('browser.download.manager.showWhenStarting', False)
profile.set_preference('browser.download.dir', os.getcwd())
# following properties to suppress download popup screen
profile.set_preference("browser.helperApps.neverAsk.openFile", "text/csv")
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/csv")
# initialise driver with above profile
driver = webdriver.Firefox(profile)
#make the request to the url
driver.get('https://api.instagram.com/oauth/authorize/?client_id=#################&redirect_uri=#############&response_type=token')
#browser.current_url
driver.implicitly_wait(5)
#Enter username and password
Username = driver.find_element_by_css_selector('#id_username')
Username.send_keys(USERNAME)
Password = driver.find_element_by_css_selector('#id_password')
Password.send_keys(PASSWORD)
#SignIn button click
SignIn = driver.find_element_by_css_selector('.button-green').click()
正如您所看到的,我正在尝试验证Instagram应用程序。我无法传递包含特殊字符“$”的密码的正确值。我收到以下错误。
